GEORGE VOELKER, OF ST. PAUL, MINNESOTA.

TYPE-WRITING- MACHINE.

Specification of Letters Patent.

Patented Sept. 14, 1915.

Application filed November 23, 1909. Serial No. 529,573.

To 117i whom it may concern:

lie it knowirthat I, GEORGE VOELKER, a citizen of the United States, residing at St. Paul, in the county 01 Ramsey and State of 5 Minnesota, have invented certain new and typewriting machines of the class known its front strike or 'writing in sight machines, wherein the type is arranged to strike the platen in front and in a plane vertical or vertically inclined, and wherein the ribbon is supported in a vibratory carrier; and further of the class wherein the carriage is releasable from its escapement or locking de'. vices through the actuation of a finger key at the key b ard; and still further of the class wherein the type carrying bars are pivotally hung in a vertical, or vertically inclined, plane and arranged concentric to the printing point.

Miy invention relates more particularly to means for actuating the printing instrumentalities independent of'the movement of On machines of the class above referred to, the writing of ,lines consisting of dots,

dashes, or other marks, becomes a tedious and tiresome task, consuming much time and energy. in that'it involves a continuous and successive depressing and releasing of a key or key lever by the operator of the machine.

This consumption of timevand energy, not

only works a hardship upon the operator of the typewriting machine but has effectually limited the usefulness of the typewriting machine, itself, in that it' has been found 40 profitable and safer. to do some classes of work with the pen on lined paper, in orderto avoid confusion and sometimes costly errors. that arise through the absence'of lines to guide the eye of the reader. For example in the billing of goods on writing machines of the class above referred to, where longcolumns of items and their prices are widely separated by blank spaces, the reader not infrequently resorts to the use of a straight 60 edge or ruler to guide the eye across the sheet. \Toconncct the columns thus sepa rated ith lines of dots or dashes on a typewriting machine in the ordinary Way would consu'm too much time. The usefulness of the present typewriting machine is still further restrained in that classes of work 1'e-.

quiring vertical lines (such as the insertion of special columns in billing) must be done by hand.

The object of my invention is particularly to provide improved means for writing lines consisting entirely or in part of periods, dashes or other marks in rapid succession without. the usual attendant tedious labor and expenditure of time.

A further object is to provide improved means for underscoring words, or groups of words, rapidly and accurately as by means of overlapping dashes.

A still further object is to provide improved means for writing dotted lines by supplying auxiliary marking mechanism without disturbing the regular printing instrumentalities, without. disturbing the usual typebars, but nevertheless striking the same ribbon in the same place that is struck by .the aforesaid instrumentalities.

A. still further and more specific object is to provide improved means for writing vertical lines of overlapping dashes or lines of dots on the paper carried by the platen.

To the above and other ends, the invention consists in the features of construction combination and arrangement of parts hereinafter more particularly described and claimed.

My invention is shown as applied to the well known Remington front'strike type-' writing machine, but it is to be understood that sa d lnventlon may be embodied 1n other forms of wrltmg machlnes, including those of the flat and stationary platen type.

.lleferringagz ain to Fig.1 of the drawings, the invention comprises an air compressor L and an air engine connected byv a pipe conductor 4%. For the purpose of co mpressing air and passing it through the conductor into the engine, the compressor 2 is provided. with the comparatively heavy cylindrical piston 5, said piston fitting snugly and slidably in the vertically arranged cylinder (3, said cylinder having an open top through which the piston may,

.pass and a closed bottom 7. Adjacentto the bottom, and piercing the side walls of the cylinder 6 are openings 8 and 9. The opening 8 is provided with a flap valve com The opening 9 leads into the cylindrical chamber 12, which is surrounded by a shell 13 and formed interiorly in that half of its length' farthest from the cylinder, with three longitudinalribs 14, said ribs forming abutmentsfor the valve disk 15, the interstices between said ribs serving as air passages when the valve abuts against the ends-of said ribs as shown in Fig. 3. At its outer end the chamber 12 leads into the pipe conductor 4. The/valve 1.5 is symmetrically notched as at '15 to form air passages. The piston diameter at its-top is reduced to form a central stem 16, which terminates in a forwardly projecting curved hook 17, said hook havmg'on its inner edge, intermediate of its length, a pointer 18. To receive the curved neck at 19 of the hook 17 when the piston is sunken in the cylinder the cylinder has in its upper edge a slot 20 The frame A is provided with a forwardly projecting finger ug A at the top of the post A. The cylinder as shown on the drawin 'sis integral with the corner post A of he frame A. Screw fastened on the front of said post, and extending downwardly and overlapping the. upper portionof the cylinder 6, and arranged to be conveniently seen by the operator of the keyboard, is a scale 21, the object of which will be hereinafter more particularly described. Near the top of the cylinder, and preferably integral therewith is a supporting arm 22, saidarm projecting in the direction of the carriage travel and parallel thereto. At its outer end said arm slidably supports a finger key 23 the square andal.

shank 24 of which fits'slid ably in the i nabuts a spring 29,. the oppositeend of whichengagcs the slidably mounted collar 30, which. surrounds looselytheth-readless por t'ion 31 of said shank. The collar 30 is pro- .videdwith an ear to which is attached one end of a chain 34, the tension rod 35 having connection with the other end thereof, and

passing through an opening 36 in the top of the plate of frame A, the rod terminates in a head 37, said head being slidably and rotatably loosely fitted around the friction rod 38, said friction rod resting on a pair of friction blocks 39 which are preferably integral with the top plate of frame A. The friction rod, 38 is provided with head 40 and a collar 11 at its inner end, the intervening portion of the rod between said head and collar being slidably fitted into the verti 'al slot 42 of a lug 43, said lug being preferably integral with the front bar 44: of

the carriage. The tension rod 35 has, intermediate of its length. turnbuckle connection 35" to admit of length variation.

The linger key 23 has a downwardly projecting forked extension 45. a fork 46 being adapted to straddle one. of the type bar keys,

the tines thereof being of sufficient length to maintain engagen'ient with the type bar key during its actuation. The finger key '23 is arranged to engage one of the column selectorkcys J in its downward movement. The rod 31 with spring .29 and rod 35 may be termed a spring-mounted device.

The conductor pipe 4 extends from the shell 13 iirthe outer head 13 of which it has air tight connection. to the left side of the machine. then extending upwardly within the front left hand corner post to the top of the machine, from which latter point it leads radially or diagonally in the direction of the printing point 47. having airtight connection with the-air engine 3.

The air engine 3" is so arranged that its longitudinal axis is approximately radial to the printing point. and at a suliicient angle in an approximately horizontal plane to the longitudinal axis l)? of the platen (the drawings showing it at about 45) to fairly clear thepath of the type on the type bar J* when it is actuated to swing its type end through an arc to the printing point. The engine is arranged approximately on a level with the longitudinal axis of the platen. The. airengine is provided with a fastening plate It which projects at an angle from its side and is prcfrraliily integral therewith,

and has a pair of slotted holes {19 to receive the screws 50, whereby the engine is rigidly fastened to the frame A. ()u the engine and 'l'irojecting rearwardly and toward the printing point 47 and terminating adjacent to the left arm E of the ribbon carrier, and in front of the ribbon, is the finger 51,0211- rying at its outer end the vertical stop pin 52. thus forming a support and guide for the liner carrier. It will be here noted that the ribbon carrier is not central with the print-' ing point, the arm E having been arranged farther to the left of said printing point, to

accommodate the liner holding mechanism which may be described as follows: The

piston rod 53 which is central'with the engine bore and alines therewith is formed at its outer end with a plate of slidable on finger 51 offset and having an offset slot 55 arranged parallel to said piston rod. said otlset being in the direction of the platen B, the slot being adapted to receive snugly the stop pin The plate 54 is comparatively long and narrow, the forward long edge thereof coinciding with the axis of the piston rod. The marking end of said plate, or the narrow edge nearest the platen. is formed pa 'allel to the longitudinal axis of the platen. The plate is well rounded at 5 5 to avoid cutting the ribbon during printing operation. Along said narrow edge and on the top of the plate 54, is a clamp lug 56 having a lever lug 57, pierced'freely by the screw 58, which latter has screw thread engagement in the plate 5+ thus forming a clamp to frictionally engage the bearing 5!). The lug 5G is bored to rotatably receive'the journal bearing portion 59 of the liner car rier'tit). The bearing portion carries at its outer end a liner 61, which may be turned from horizontal to vertical position by turning the bearing 59 in. the clamp lug 56 as by means of the carrier (30. It will be noted that the carrier is so bent that its longest portion will be parallel to'and just over the piston rod, when the liner (31 is in horizontal position as shown in Fig. 8. Theball (52 serves as a finger hold.

The engine 3 comprises the pressure case (i3, inclosing the distributing valye- 64 and striker. or piston 65 the lattercarrying the 100 piston rod 53. The case 63fissnpplied with constant working pressure from the cylinder 6 through the pipe 4. 1 p

The distributing valve (34 comprises a cylinder for the head (36 of the striker (35 to 105 operate in, and said valve (Set is reduced in diameter at ($7, the latter part performing which at the position shown in Fig. 11 admit air from the case (33 to the chamber 70 and an exhaust port or ports 71 which at the position shown in Fig. 12 exhaust air from the chamber 70 to atmosphere through open- 7 ing 72. The striker or piston 66 is of re- 11 duced diameter at 73, said reduced portion being slida-bly fitted in the fixed sleeve 74, the reduced portion forming a supplemental chamber 75, said chamber being constantly exposed to the Working pressure in the case 63 throughthe port 76. The pressure in the chamber 75 serves to return the striker, while the pressure on the shoulder 77 of the valve serves to return the latter, each moving toward the other when pressure is exhausted from the chamber 70 through the port 71, Fig. 12.

he inward stroke of the valve 64 is lim-- ited by its abutment against a cushion 79,

and the retiring stroke of the striker (55 is plurality ofsuccessive forward and back-1 ward strokes, the marking end of the carrier striking the 11bl)0l1 and the paper covered der constant pressure, enters through the port (39 and acting on the enlarged surface area of the striker drives the same with force against the platen through the medium of the piston rod 53 as shown in Fig; 12. The pressure then acting on the valve (il reciprocatesit until the exhaust port 71 extends beyond the end of the bushing or valve seat 82 where the prevailing body of air is exhausted. The pressurein the chamber 75 acting on the shoulder 83 of the striker returns the same to its inner position as shown in Fig. 11. The air pressure then acting on the shoulder 7 7 of the valve moves the valve until the port 69 is again openrfor the induction of pressure and the same movements are repeated. A spring 84 is interposed between the head 63 and the striker 65. As shown in the drawings the air chamber 85 of the cylinder is sufliciently large, as compared with the air chambers and of the engine, to supply through the pipe conductor 4, and through the medium of the descending plunger or piston 5 a sufficient quantity of compressed air .to cause the striker 66, and therefore the piston rod and the liner or marker oarrier,-to make a platen with every forward stroke and printing an impression of the liner on said aper. It is intended that the cylinder cham er be of sufliciently ample proportions to furnish enough air for the writing of a full line 5644f marks across asheet of -paper.-----"" It. will be evident that the weighted piston 5' insures a uniform pressure in the chamber 85 during its "entire downward stroke, in that the weightis constant, thus impartingto the piston or striker, and therefore .to the liner 61 uniform consecutive vibrations, whichrin' turn insures equidistant and. regular impressions of the liner on the paper carried by the platen.

The operation of the invention is as follows: In normal position the piston 5 is sunken in the cylinder 6, the neck 19 of' the hook 17 resting on the bottom of the slot 20 in the cylinder wall. The liner (i1 is normally (when the invention is out of use) in a receded, or partially receded, position (Fig. 6 showing the liner. fully receded from the platen) its position depending upon the position of the-piston 65, which is free to stop at any point between the spring 84 and the cushion 80, asshown in Fig. 11, the spring 8i performingthe combined functions of a cushion and a means for preventing the liner 61 to stop at the printing point (Fig. 7) and thus block the path of usual typebars of the machine.

When the piston under pressure in its for ward stroke carries the liner against theplaten the impact compresses the spring 84, which, in turn, causes the p1ston to rebound,

carrying the liner with it, thus makin interference with the type bars impossib c,'as shown in Fig. 6 in which a type bar J is shown in dotted lines.

In order to. avoid the paths of the type on the type bars H, I arrange the engine 3 at an angle with the longitudinalaxis of the platen, as has been previously explained. Withthis arrangement of the engine 3 the piston and therefore the liner strike the platen at an angle, with a general tendency to glance off in a resultant direction after contact with the platen, In order to counteract the referred to tendency of the glancing off of the liner, I have located the engine to the left of the printing point, so that the direction of the piston rod 53 in its forward printing stroke will be opposed to the direction in.which the carriage is traveling durin printing operation. Thus the platen on t e moving carriage in opposing the direction of the striking piston tends to re the liner during the moment of impact an thus prevents slipping and dragglng, which would result in blurred impressions on the paper.-

To-further control the liner during con tactwith the platen, the finger 51 and its pin 52 are provided; the pin fitting snugly into the slot 55 of the plate 54, said plate,

working back and forth during printing operation. The pin 52 is so arranged on the finger 51 that the arrival of the pin at the end of the slot 55, and'the-arrival of the liner "G'II at the printing point 47, occurs simultaneously (Fig.7). Thus the direction of the fore in the'piston rod 53, through the medium of the pin 52, is diverted into a resultant direction nearer to right angles with the longitudinal axis of the platen. The engine bracket 48 is provided with slotted holes 49, by means of which the liner 61 may be adjusted to be brought nearer to, or farther from, the printing point. It will be evident that the rate of speed atwhich the carriage travels past the rapidly vibrating liner will determine the space which sepae rates the written dots or dashes on the paper. To use only the column selector keys for releasing the carriage without providing a brake retarding means for checking its speed would be impracticable, because the carriage would travel too fast. To control. the speed of the carriage I provide the friction rod or wire 38 which is attached to the carriage as byineans of lug 43. lVhcn the key 23 is depressed the chain 351 will be drawn taut,

amount of pull in the rod 35, which is ac-- eomplished by shortening or lengthening the same as by means of the turnbuckle 35. The spring 29 affords a cushion as well as permitting the key '23 to be still further depressed for the purpose of actuating the keys K and J. The rod 35 should be so adjusted by the use of the turnbuckle 35, that pressure will be brought to bear on the rod 38 just after the carriage has been released by the depression of the key J. There is in all tabulat'orkeys a slight surplus of downward travel after its function of releasing the carriage has been performed. Thus the spring 1 9 may be still enough to exert sullicient pressure in a depression of but one-sixteenth of an inch. it is intended to have the head 37 still. hanging loosely until just after the carriage is released. (See Fig. 1). It will. be noted that the cup nut 26 also permits of adjustment to vary the amount of depression of the key J. The head 37 35) may be termed retarding devices. The spring 29 and the chain 3t render the connections between the carriage and the tabulator mechanism both elastic and .fieXible.

The dvg'n .ion of key K will depress the uni 'ersal bar M at M and thus actuate the ribbon ()ll'l'l jl' it through the medium of the lever (,1. rod 1, crank rm 0, rock shaft L, and crank arms and links N. The fork 46, however. is designed to depress the key lever K sufficient only to swing in an arc the type of its corresponding type bar H, said bar turningon its pivot a through the lever pivot o in the frame A (Fig. 21) through but a fraction of its stroke, thus preventing interference at the printing point with the liner (31, during printing operation but nevertheless raising the ribbon carrier from the dotted line 0 to the dotted line i, as shown in Fig. in, path of the liner 61. and over the printing point 17. The key J 1s the usual column selector key of the Remington machine, whereby the carriage is released and caused to travel to left through the medium of the spring drum G. Fig. 16 shows the general principle employed. the depression of the kev J actuates the fulcrumcd lever T as by means of rod S thus raising-the rack X about its pivots a. and disengaging the pinion lV. which latter is normally held locked as by means of wheels YY, and dog Z,

and the blocks thus b inging the ribbon into the said wheels and pinion being rigidly mounted on the shaft Thus it will be evident that the depression ofkey 23 results in the release of the carriage fromits locking devices, causing it to travel to the left through the medium of the spring drum G, the controlling of the speed of the carriage and the raising of the ribbon into the type path. If,

now, the operator places the thumb of the right hand on the finger lug A and with the forefinger catches the hook 17 from below, pulling it, with the piston 5 upward, the flap valve 10 will move inwardly through the medium of the atmospheric pressure outside the cylinder and the vacuum created in the chamber 85 by the rising piston. Air will rush into the cylinderthrough the opening 8, until the piston has reached its'extreme height (Fig. 1). During the pistons upward travel, the valve 15 will close the opening 9, due also to atmospheric pressure Without and the vacuum within the chamber 85, thus preventing the actuation of the'engine by the rushing in of air through the port 72, which would occur during the rise of the piston 5 if the opening 9 were left open.

If, now, the operator removes his hand and allows the piston to descend into the cylinder 6 by its own weight, the valve 15 will be forced against the ribs 14 in'the chamber 12 and the air will pass through the notches 15 in the valve 15 into the pipe 4: and into the engine 3, causing the piston 65 to reciprocate or vibrate rapidly and therefore also the liner, said linerstriking the ribbon and paper covered platen with every forward stroke. When the liner at the end of the piston rod 53 in its rapid movement forward collides with the moving platen, the two are instantly separated by the spring 84, the impact of the blow being suflicient to make imprints through several carbon sheets. If the impact is found too great and the platen becomes pitted, the engine may be adjusted by means of slotted holes 49.

r The reciprocating piston 65 of the engine may be stopped instantly by depressing the button 11 on the flap valve 10 which effects the rushing out of the air in the chamber a d the rapid descent of the compressor piston It will be evident, then, that in order to write full lines of dots, dashes, or other marks, across a sheet fro-m left to right, it is simply necessary to lift the compressor piston 5 to its upward limit, with the right hand, and with the left hand depress the key 23 to its downward limit. If, however, only short portions of dotted lines are required the piston b nnay be raised to any desired mark on tlie'scale' hook 17 i11cli.oatingtlie level of said piston. Thusthe pistoriai may be raised to write any desired length of line on the paper, thus obviatingthe necessity of using the button 11 ex pt on special occasions orin emergency,

21, the pointer 18 on the.

and of raising the piston to its full height except when necessary. The scale 21 is marked to correspond with the scale I. forexample, it is desired to write dotted lines from the point 50 on the carriage scale, it is only necessary to raise the piston 3 to the 50 mark on the scale 21, and allow the piston to descend.

It will be evident from the foregoing that the liner (31 may be reciprocated without using the key 23 at all, or, in other words, the carriage may remain unmoved during the actuation of the engine 3.

7 Referring to Fig. 8 it will be noted that the liner 61 is not'mounted cent-gal on the portion 59 of the carrier, but thiit the end 61 to the left of the portion 59 is considerably longer than the portion to the right of the portion 59. Referring to Fig. 9 the carr er 60 is shown in upturned position, the liner 61 standing vertical, the carrier GO having been turned in the journal box 56 until the liner 61 abuts against the stop pin 56 (Fig. 8) which limits its movement. The long end 61 of the liner 61 is now turned downwardly and projects beyond the upper edge of the ribbon F when said ribbon is in its normal position as shown in Flg. 9. If, now, the liner 61 is reciprocatedit will print an impression on the paper "of that portion of itself which extends below the upper edge of the ribbon F, thus obviating the necessity of raising the ribbon carrier. It will be evident that if the operator turns the thumb wheel B with his left hand, at the same time holding the platen carriage stationary, and raises the piston 5 with his right and then allows it to descend and then turns the handle I) with his right which moves the ribbon from one spool to the other, the liner 61 will write vertical lines of dashes or solid lines,

according to the speed at which the thumb Wheel B is turned.

The ribbon mechanism actuated by the handle D is not shown, but it is to be understood that the invention is shown as applied to a Remingtonfront strike machine, which has a handle D on either side of the machine for transferring the ribbon from one spool to the other.

It is obvious that the-details of the device may be variously modified'wi'thout departing from the principles of the invention, the scope of Which is defined in the claims.
